      Metal Closures

Metal Closures - Tried, tested, trusted

Compatible with metal, glass and plastic containers.

Offer excellent product differentiation, available in a wide range of profiles and suitable for most food and beverage products

Suitable for all filling processes including hot fill, cold fill, pasteurisation and sterilisation

Provide excellent platform for high quality multi-colour print decoration

Excellent barrier performance against UV light and oxygen resulting in long shelf life for sealed products

Hermetically sealed metal vacuum closure system ensures food preservation

Can provide tamper-evidence, are reclosable and offer good abuse resistance

Can offer fast heat transmission thus reducing cost and CO2 emission

Major markets being: Cooking Sauces, Dressings & Condiments, Preserves & Honey, Pickles & Babyfood

Recycling rates determine carbon emissions 

Recycling rate is the percentage of cans recovered and recycled as a percentage of cans placed on the market in the year.

All metal closures returned for recycling are recycled.

Steel and aluminium can be recycled again and again without loss of quality.

More recycling means less CO2.

More Recycling of Metal Closures Means Less CO2 

Currently there is no universal approach for the measurement of a carbon footprint.

A European carbon footprint model is available to trade association members.

The higher the recycling rate the higher the carbon saving. click here for chart

Metal operates in a ‘material to material’ loop – whether the material comes back in exactly the same product is not relevant.  This 'End of Life' approach most accurately reflects the emissions from metal Click here for the Material to Material Loop diagram

When recycled, the carbon (energy) embodied in a metal closure will displace new energy in the steel and aluminium production processes - whether the end use is in the form of a car, bridge or can.

Embodied carbon is the carbon dioxide that is emitted at all stages of a good's manufacturing process, from the mining of raw materials through the distribution process, to the final product.

Life Cycle Assessment is the detailed assessment of the environmental effects of a process, product or service 'from cradle to grave'.  However the boundaries need to be carfully and clearly defined - where you start and finish, what is included, what is excluded, all have a major impact on the findings of an LCA and depend on the resources used for the study.  This can often lead to problems when two apparently similar studies are compared.

Metal used to make metal closures is produced from both virgin and recycled materials 

Recycled content for an individual closures cannot be determined due to the homogeneous nature of the material (CEN Standards).

In Europe metal is on average produced from 50% recycled material.

Recycled content is the figure for the scrap steel consumed or secondary smelted aluminium as a percentage of total steel or aluminium production.

High recycling rate reduces net weight to landfill 

  • Net weight to landfill is determined by the weight of the pack relative to its recycling rate.
  • Higher gross weight packs with high recycling rates may well reduce landfill.
  • All packaging is less than 3% of all solid waste and 60% is recovered and recycled. *
